ENGINEERED POWER SOLUTIONS 72 SOUTH MAIN STREET, SUITE A TEMPLETON, CA 93465 Solar Warehouse Rail Analysis – Generic Packet 1.0 – RESULTS & SCOPE OF WORK 1.1 – Overview of Analysis & Results • Governing Building Code: 2022 California Building Code (CBC) based on the 2021 International Building Code (IBC) and referencing the 2016 Minimum Design Loads for Buildings and Other Structures by the American Society of Civil Engineers (ASCE 7-16) including all supplements and errata. • Project Description: The project consists of the determination of the max span for the proposed rails to be used as a flush roof mounting system for Photovoltaic (PV) modules. The solar designer, Solar Warehouse (SWH) has contracted Engineered Power Solutions (EPS) to address the structural aspects of the rail, mainly the rail span of the proposed rail concepts. SWH has specified a number of common design scenarios that EPS has used to determine the maximum allowable rail spans for the (2) rail profiles proposed (Standard and Ecolite). These scenarios include design wind speed, wind exposure category, design ground snow load, orientation of module, tilt (pitch) of the roof/modules, roof zones, etc. SWH has also specified a number of design assumptions that remain constant for all scenarios which are discussed in further detail on the following pages. Design and specification of the anchorage methods and fasteners that shall support the rail spans listed in this packet is by others since the anchor type is dependent on the existing building roofing and/or framing. It is also the responsibility of others to ensure any other hardware other than the rails (module clamps, components that anchor the rails to the existing structure, etc.) is structurally adequate for the imposed module, rail, and anchorage loads. This packet address the rail spans only. Page 3 2004 W Picasso - 2018062008/29/23
